HTTP and HTTPS Auto-Binding

Payara Micro supports an auto-binding feature for its HTTP and HTTPS port,
allowing Payara Micro to dynamically find a free HTTP or HTTPS port as required
during startup.

This feature is controlled through these three options:

--autoBindHttp

Enables auto-bind functionality for the HTTP port

--autoBindSsl

Enables auto-bind functionality for the HTTPS port

--autoBindRange

Sets the range for the auto-bind feature

When auto-binding is enabled, Payara Micro will attempt to connect to the port
specified with the --port or --sslPort option (or, if these options are not
specified, to port 8080 and 8181 respectively), and if that port is busy,
it will instead try to bind on the next port up, repeating this process until
it finds a free port, or the --autoBindRange limiter is reached.

For example, if ports 8080 and 8081 were busy, and ports 8082 and 8182
were free, then starting Payara Micro with the following command would have the
HTTP port bind to 8082 and the HTTPS port bind to 8182:

Be aware that the auto-bind feature does not currently read port values from
domain.xml files; if the --port and --sslPort options are not used, then
the --autoBindHttp and --autoBindSsl options will assume that the HTTP and
HTTPS ports will be at the default values of 8080 and 8181 respectively.
